The toxic waters of Buxton’s blue lagoon have frozen over as the UK becomes submerged by heavy snow. A video shows the lagoon completely frozen over and blanketed in heavy snow. The amazing footage was shared by a Twitter user, who posted: “When it’s so cold the #blue lagoon at #buxton freezes. #snowuk”. Its clear blue waters may seem inviting, but the flooded former quarry is so polluted that its contents are nearly as toxic as bleach.
